摘要
经计算并和常规布局大型飞机对比分析,给出了盒式机翼布局大型飞机的气动特点;然后研究了盒式机翼布局大型飞机本体横航向飞行品质;针对盒式机翼布局本体飞机横航向飞行品质较差的问题,研究了提高盒式机翼布局飞机横航向飞行品质的有效方法。研究结果表明:盒式机翼布局大型飞机具有良好的升阻特性和特殊的横航向气动特性;修改布局参数对提高盒式机翼布局飞机横航向飞行品质是有限的,控制律的设计可以保证其具有满意的横航向飞行品质。
Compared with a large aircraft with conventional configuration,the aerodynamic characteristics of large aircraft with box-wing configuration were calculated and showed in this paper.The lateral-directional airframe flying qualities of the large aircraft with box-wing configuration were researched.The lateral-directional airframe flying qualities of the large aircraft with box-wing configuration will be deteriorated,so the effective measures which can improve flying qualities of large aircraft with box-wing configuration would be researched.The results show that the large aircraft with box-wing configuration has a larger ratio of lift to drag and special lateral-directional aerodynamic characteristics.Modifying configuration parameters are limited to improve the lateral-directional flying qualities of large aircraft with box-wing configuration and the design of control laws can assure satisfied flying qualities.
